poj 2503 Babelfish(Map、Hash、字典树)

题目链接:http://poj.org/bbs?problem_id=2503

思路分析:

题目数据数据量为10^5, 为查找问题,使用Hash或Map等查找树可以解决,也可以使用字典树查找。

 

代码(Map实现):

#include <iostream>#include <sstream>#include <string>#include <map>using namespace std;int main(){    char word[15], foreignWord[15], strStream[25];    map<string, string> dictionary;    while (gets(strStream) && strStream[0] != \0)    {        sscanf(strStream, "%s%s", word, foreignWord);        dictionary[foreignWord] = word;    }    while (cin >> foreignWord)    {        if (dictionary.find(foreignWord) != dictionary.end( ))            cout << dictionary[foreignWord] << endl;        else            cout << "eh" << endl;    }    return 0;}
